Abstract
A device and a method are provided for measuring the moisture in die cast molds, the cavity of which is connected via an evacuation conduit to an evacuation device. The modular assembly of the device is connectable to the evacuation conduit and includes a sensor assembly to measure the moisture of gases evacuated from the mold cavity. The sensor assembly includes an emitter emitting electromagnetic radiation and a detector detecting electromagnetic radiation. On the basis of the measured values obtained during the evacuation action it can be determined whether the amount of a water/release agent mixture jetted into the mold cavity needs to be altered before the actual casting action.
Claims17
A device for measuring the moisture in die cast molds, a cavity of which is connected via an evacuation conduit to an evacuation device, characterized in that said device is connectable to the evacuation conduit and comprises a sensor assembly by means of which moisture in gases exhausted from the cavity is measured, wherein
- said sensor assembly includes at least three LED emitters emitting electromagnetic radiation and a corresponding at least three detectors for detecting electromagnetic radiation;
- the device is provided with a duct for conducting the exhausted gases, the duct passing through between the at least three LED emitters and the at least three detectors;
- and
- said duct defines a cross-section and said at least three LED emitters and said at least three detectors are arranged distributed over the longitudinal cross-section of the duct.
